I vote for The Planes in Spain because that is what the last two people above me voted for. It keeps the streak going.
I only count four engines in the picture. Where are the other two? :huh:
A shot of the re-built 521 on a test flight in the countryside near Toulouse, an aerial shot being necessary to highlight its distinctive hull form. The six Hispano-Suiza 12Ydrs engines are also clearly visible, the inboard four being in the tractor push/pull arrangement so popular in seaplanes. The switch from four engines to six was forced upon Latécoère after Hispano-Suiza abandoned development of the planned engine, the 18Sbr. With it’s unusual three block ‘W’ cylinder layout the 18Sbr was originally intended as a racing engine to challenge for the 1929 Schneider Trophy, however ongoing problems during development meant the first engine didn’t enter testing till after the Schneider race for that year had been run and won by Britain with the Rolls Royce 'R' powered Supermarine S.6. This disappointment, along with ongoing reliability problems and the failure of the test engines to meet the hoped for power outputs, led to the engine’s cancellation. The ongoing problems at Hispano-Suiza with engine development, and the affect this had on otherwise promising designs, would be a recurring theme in French aviation throughout the decade.
